Nonsurgical Reduction of the Interventricular Septum in Patients with Hypertrophic Cardiomyopathy

Abstract

Nonsurgical septal reduction leads to sustained improvements in both subjective and objective measures of exercise capacity in association with a persistent reduction in resting and stress-induced left ventricular outflow tract gradients. It is also associated with a high incidence of procedure-related complete heart block, however, often requiring permanent pacing.
